For lack of anything better to write, here is an excerpt from P.G. Wodehouse's 'Right Ho, Jeeves'
"The discovery of a toy duck in the soap dish, presumably the property of some former juvenile visitor, contributed not a little to my new and happier frame of mind.What with one thing and another, I hadn't played with toy ducks in my bath for years, and I found the novel experience most invigorating. For the benefit of those interested, I may mention that if you shove the thing under the surface with the sponge and then let it go, it shoots out of the water in a manner calculated to divert the most careworn. Ten minutes of this and I was enabled to return to the bed-chamber much more the merry old Bertram".
